Welcome to 2013's Battle Arena Otaku Fight! Fight!, MTV Geek's annual brawl between the biggest and best in characters from anime, manga, and Japanese pop culture characters. Not only will we get a chance to spotlight some of most interesting, most intriguing, or simply odd characters from 2013, but it's also a chance to you to have your voice heard. You know the drill: we'll present the matchup, and you the reader will get to choose which character comes out on top. So which mech, heroine (or hero), monster, or mascot will come out on top this year?

Billionaire playboy inventor vs. high school badass. The carnivore tomboy against the man in the iron suit. Who will win?

This year, Iron Man received his second animated project from Madhouse Studios with the feature-length "Rise of Technovore." That OAV introduced a nanotech foe for Tony Stark/Iron Man who found himself in the crosshairs of S.H.I.E.L.D. with the Punisher as an unlikely ally. Sure, "Rise of Technovore" may not have made the same splash as Iron Man's third big-screen foray, but it was another chance for Japanese audiences to get some Stark time and see what the Invincible Iron Man could do in other media.

His challenger had her own crossover into other media last year: "Persona 4" karate-obsessive and serial snacker Chie enters the Arena this year after being featured in not only "Persona 4: The Animation" but Atlus' "Persona 4: Arena" fighting game (along with the Vita update to "P4," "Persona 4: The Golden"). Brash with a secret soft side, loyal almost to a fault, and the one character pretty much every "Persona 4" fan agrees they'd want by their side.

But will her fans be loyal in return, picking her over the man in the world's most famous suit of armor? Or will Tony Stark's endless charisma be overcome by his greatest weaknesses--a dangerous woman?
